Banned from clan server with no website

[MykeGregory]

So i'm banned from a server that is owned by a clan with NO contact details (That i was able to find)

i am banned on both [ESP] france servers.
I have come here for 2 things; 1) i dont want to be banned on these servers, its clearly a range ban or something.
And 2)How can i avoid this problem in the future, regarding contacting the admins of these clans that have no page on the wiki.
